[Zope] Newbie: TAL Conditions

| Hello all,


[snip]

| This works fine.  However, where there isn't a record (i.e. an empty string), a
| <TD> will not be defined so that it leaves ugly gaps in the table.  To ensure
| that a '<TD>&nbsp;</TD>' replaces an empty string '' I added two tal:condition
| statements.  This works, but is sort of ugly looking as, in my head, it is the
| equivalent of two 'if' statements when it should be an 'if/else'.  The below
| code works, however is there a cleaner way to do this?

Probably millions of ways... here's one.

| 
| ### START CODE ###
| 
| <table border="1">
|   <tr><th>Date</th><th>Server</th></tr>
|   <tr tal:repeat="transfer container/getTransfers">
|     <td tal:content="structure transfer/time_stamp">time_stamp</td>


Replace this;

|     <td tal:condition="python: transfer.server==''">&nbsp;</td>
|     <td tal:condition="python: transfer.server!=''"
|         tal:content="structure transfer/server">server</td>

With this;

<tal:block define="theContent python:test(transfer.server, transfer.server,'&nbsp;'">
<td tal:content="structure theContent"></td>
</tal:block>
	

|   </tr>
| </table>
| 
| ### END CODE ###
